ABSTRACT:
A tool member is arranged for ease of removal of broken sprinkler tubes typically formed of PVC pipe. The tool structure includes an elongate plate having a handle orthogonally mounted adjacent an upper distal end thereof. Projecting to the lower distal end from the spaced sides of the plate are canted side extensions defining an acute angle therebetween for projection into a broken conduit portion permitting its rotative threaded disengagement relative to the sprinkler structure. A modification of the invention includes a saw blade arranged for ease of severing of fluid conduit, as well as an extractor structure arranged for impact extraction of the broken tubular portion.
